I definitely wasn't in the mood for something like this today. After talking with a friend afterwards, I've realized I failed to connect with it mainly because I didn't do military service and I'm not familiar with almost any army practices. This is undoubtedly extremely well-shot, and the overall direction is great. Feels like a very singular experience, for better and worse. The editing in particular was really odd, even quite terrible at points.
Having a better understanding now, I'll give it another watch in the future, and hopefully I'll be able to connect and even like it!
